我正在尝试下载这个 gem https://github.com/heartcombo/mail_form我收到这个错误 undefined method `deliver' for # In the gem file

   gem 'mail_form'
    gem 'rails', '4.2.11.1'

在 production.rb 文件中

config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    address:              'smtp.gmail.com',
    port:                 587,
    domain:               'gmail.com',
    user_name:            'gmail email',
    password:             'gmail password',
    authentication:       'plain',
    enable_starttls_auto: true  }

在接触控制器

类 ContactsController < ApplicationController 需要 'mail_form' def new @contact=Contact.new end

  def create
    @contact = Contact.new(contact_attributes)
      if @contact.deliver
      redirect_to new_contact_path, notice: "Thank you... Your Message was sent successfully."
      else
        flash.now[:error] = "Please correct the form"
        redirect_to new_contact_path
      end
  end

  def index
    @contact=Contact.all
  end

  private

  def contact_attributes
    contact_attributes = params.require(:contact).permit([:name,:email,:message,:phone])
  end
end

在 new_contact_path

 <%= form_for @contact do |f| %>
                        <div class="col-sm-5 col-sm-offset-1">
                            <div class="form-group">
                                <label>Name *</label>
                                <%= f.text_field :name, class: "form-control" ,required: "required" %>
                            </div>
                            <div class="form-group">
                                <label>Email *</label>
                                <%= f.text_field :email, class: "form-control", required: "required" %>
                            </div>
                            <div class="form-group">
                                <label>Phone</label>
                                <%= f.text_field :phone, class: "form-control" %>
                            </div>                      
                        </div>
                        <div class="col-sm-5">
                            <div class="form-group">
                                <label>Message *</label>
                                <%= f.text_area :message , id: "message",  required: "required", class: "form-control" ,rows: "8" %></textarea>
                            </div>                      
                            <div class="form-group">
                                <%= f.submit "Submit Message"  %></button>
                            </div>
                        </div>
                        <% end %>

在接触模型文件中

      def headers
        {
          :subject => "My Contact Form",
          :to => "nourfiverr@gmail.com",
          :from => %("#{name}" <#{email}>)
        }
      end

为了使用mail_formgem，您需要创建另一个模型，如描述中的那样，或者您需要修改现有模型。您不能直接使用这些行

contact_attributes = params.require(:contact).permit([:name,:email,:message,:phone])
@contact = Contact.new(contact_attributes)
@contact.deliver

在这里交付对于像这样的模型没有任何意义，class Contact < ApplicationRecord直到您使您的联系模型像这样

class Contact < ActiveRecord::Base
  include MailForm::Delivery

  attributes :name, :email, :message, :form

  def headers
    {
      :subject => "My Contact Form",
      :to => "nourfiverr@gmail.com",
      :from => %("#{name}" <#{email}>)
    }
  end
end

如果您不想进行此修改，只需按照 gems 自述文件中的步骤操作即可。
